Rubber heel



Patented Nov. 15, 1932 UNITED STATES HARRY HIRscHFELD, or SEA Gurn-,NRW YORK RUBBER HmanY Application mea July s, 193i. Serial -Nofsasaaf rl`his invention relates to rubber heels and it has for one of its objects the provision of a rubber heel having embedded therein a wearresisting plate. u Another object of the invention is the provision of a rubber heel embodying a wearresisting plate of novel construction, which is preferably resilient and which preferably is provided with retaining lugs of novel construction, said lugs beings also preferably resilient and extending at an angle to the plate. 1

A further object of my invention is the provision of a rubber heel having incorporated therein a wear-resisting plate adjacent the rear edge and the lower surface of the heel so that the heel will be worn uniformly.

Other objects of the invention will be appreciated fromaV reading of the following specification.

The invention will be fully and comprehensively understood from a consideration of the following detailed description when read in connection with the accompanying drawing which forms part of the application, with the understanding, however, that the improvement is capable of extended application and is not confined tothe exact showing of the drawing nor to the precise construction described and, therefore, such changes and modifications may be made therefrom as do not affect the spirit of the invention nor exceed the scope thereof as expressed in the appended claims.

In the drawing:

Fig. 1 is a plan view of my improved rubber heel.

Fig. 2 is a section taken on line 2-2 of Fig. 1.

Fig. 3 is a vertical section taken on line 3 3 of Fig. l.

Fig. 4 is a perspective view ofthe wearresisting plate shown in Figs. 1, 2 and 3, as N embedded in a rubber heel; and Fig. 5 is a vertical section similar to Fig. 2,v

but showing a modified form of wear-resistino plate embedded in the rubber heel.

eferring to the drawing for a more detailed description thereof, the numeral 7 in.-

dicates a rubber heel of any usual or pre'-v f'erred construction.` Adjacent lthe'rear edge andthe lower surface of the heel, ay wearfresisting plate Sis embeddedin the heel. The mentioned plate is lpreferably a metal plate and is preferably resilient and corrugated, ,545 the resiliency beingincreased by the-"corruga-tions. Portions 8a of the corrugated plate,

:as shown in Fig. 1, are flush 4with the lower surface o f the rubber heel While the interven- V ing portions 8b are above `the mentioned low- .6.9

er surface. The metal plate is curved to conform with the curvature-ofthe rubber'heel and it has, extending from the inner side t thereof, a plurality of tapered retaining lugs 9, said lugs being bent upwardly at an angle to the plate and therefore being more deeply embedded in the rubber heel than the plate itself. The mentioned lugs 9 are preferably resilient. The resiliency of the mentioned lugsV and theirV angularity relative to the do VVplate are effective to resiliently mount the plate, independent ofthe fact` that the plate 1s embedded in rubber'. The mentioned plate 1s also provided with end lugs l0, theser lugs also being preferably Vresilient and bent upwardly from the lower surface of the heel, the heel being regarded as attached to a shoe, and the shoe in normal position. The lugs f 10 are thus, like the lugs 9, embedded more deeply in the heel than is the plate. Theo:

lugs 9 and 10 are provided, respectively,with apertures 9a and 10a so that the rubber, when 1n the plastic state, may flow therethrough and, when solidified, securely hold the lu and therefore the plate, in position.

The modied formfof the invention shown in Fig. 5 is similar lto the form previously described except that the end lugs 12 are bent inwardly towards each other in adirection parallel to the upper and lower surface of the heel, being spaced from the wear-resisting plate8. v Whatis claimed as new is:

1. A rubber heel comprising a rubber body l and a metal plate vinterior thereto,rthe said plate being arranged'adjacent the rear edge of the heel and extending substantially parallel tothe tread face and being generally of corrugated form with the peaks of the cor- ,100

rugations' extending to said tread face of the heel.

2. A rubber heel comprising a rubber body I and a metal plate interior thereto, the said plate being arranged adjacent the rear edge of the heel and extending substantially parallel to ,the tread face and being generally ofV corrugated form with the paksof the corrugations extending to the surface bearingV face of the heel, said plate being provided with retaining lugs extending into the rubberA c, body in a direction away from said tread l face. f

3. A rubber heel comprising a rubber body and a metal plate interior thereto,'the said plate being arranged adjacent the rear edge of the heel and extending substantially parallel to the tread aceand being generally Y of corrugated forin with the peaks of the corrugations extending tosaid tread face of the heel, said plate being resilient and formed n With anchoring lugs at its extremities and on one side edge adjacent the peaks of the corrugations.
